How to create Hibernate session in Spring MVC application
I am new to Java/Spring/Eclipse. I am working on creating the login screen using Apache Tomcat 7, SQL Server, Spring MVC, and Hibernate. When the repository layer tries to create the Hibernate session, the system crashes. I am at a lose as to why. Here is the error:
PHP Code:
message Request processing failed; nested exception is org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
description The server encountered an internal error that prevented it from fulfilling this request.

The Repository:
PHP Code:
package com.accumed.protracking.repository;
@Repository("userInfoRepository")
@Transactional
public class JpaUserInfoRepository implements UserInfoRepository {
private SessionFactory sessionFactory;
public SessionFactory getSessionFactory() {
return sessionFactory;
}
@Resource(name="sessionFactory")
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
@Override
public UserInfo get(String domain, String username, String password) {
Session session = sessionFactory.getCurrentSession();
Query query = session.getNamedQuery("callUserInfoGetProcedure")
.setParameter("domain", domain)
.setParameter("username", username)
.setParameter("password", password);
List result = query.list();
if(result.size() > 0)
return (UserInfo) result.get(0);
return null;
}
}
The Entity
PHP Code:
package com.accumed.protracking.domain;
import static javax.persistence.GenerationType.IDENTITY;
import javax.persistence.*;
import org.hibernate.validator.constraints.NotEmpty;
@NamedNativeQueries({
@NamedNativeQuery(
name = "callUserInfoGetProcedure",
query = "exec UserInfoGet :domain, :username, :password",
resultClass = UserInfo.class
)
})
@Entity
@Table(name = "userInfo")
public class UserInfo {
@NotEmpty
private String domainName;
@NotEmpty
private Boolean corpActive;
@NotEmpty
private int tblCorporation_Id;
@Id
@NotEmpty
private int tblUser_Id;
// snipped code
@Column(name = "DomainName")
public String getDomainName() {
return domainName;
}
public void setDomainName(String domainName) {
this.domainName = domainName;
}
@Column(name = "CorpActive")
public Boolean getCorpActive() {
return corpActive;
}
public void setCorpActive(Boolean corpActive) {
this.corpActive = corpActive;
}
@Column(name = "tblCorporation_Id")
public int getTblCorporation_Id() {
return tblCorporation_Id;
}
public void setTblCorporation_Id(int tblCorporation_Id) {
this.tblCorporation_Id = tblCorporation_Id;
}
@GeneratedValue(strategy = IDENTITY)
@Column(name = "tblUser_Id")
public int getUserId() {
return tblUser_Id;
}
public void setUserId(int tblUser_Id) {
this.tblUser_Id = tblUser_Id;
}
// snipped code
}
The Service
PHP Code:
package com.accumed.protracking.service;
@Service
@Transactional
public class UserInfoServiceImpl implements UserInfoService {
@Autowired
private UserInfoRepository userInfoRepository;
@Override
public UserInfo login(String domain, String username, String password)
throws AuthenticationException {
UserInfo userInfo = this.userInfoRepository.get(domain, username, password);
if (userInfo == null) {
throw new AuthenticationException("Wrong domain/username/password combination.", "invalid.username");
}
return userInfo;
}
}
The Controller
PHP Code:
package com.accumed.protracking;
@Controller
@RequestMapping(value = "/login")
public class LoginController {
public static final String ACCOUNT_ATTRIBUTE = "account";
@Autowired
private UserInfoService userInfoService;
@RequestMapping(method = RequestMethod.GET)
public String initial()
{
return "login";
}
@RequestMapping(method = RequestMethod.POST)
public String loginAttempt(@RequestParam String domain, @RequestParam String username, @RequestParam String password,
RedirectAttributes redirect, HttpSession session) throws AuthenticationException {
try {
UserInfo userInfo = this.userInfoService.login(domain, username, password);
session.setAttribute(ACCOUNT_ATTRIBUTE, userInfo);
return "redirect:/index.htm";
} catch (AuthenticationException ae) {
redirect.addFlashAttribute("exception", ae);
return "redirect:/login";
}
}
}
